Description

Technical Field

[0001] This utility model relates to the field of steel cage processing, and in particular to a processing device for spiral reinforcement bars of steel cages. Background Technology

[0002] Spiral reinforcement generally refers to spiral stirrups. Spiral stirrups are one of the main components of confined concrete. Confined concrete utilizes the overall continuity of spiral stirrups to significantly improve the load-bearing capacity and resistance to damage of components, thereby achieving seismic performance that surpasses that of ordinary concrete components. When used as ordinary concrete, confined concrete can save on steel reinforcement, improve work efficiency, and ensure project quality.

[0003] The production of spiral stirrups is mostly automated. For mass production, multiple straightening devices are used, as seen in Chinese utility model patents with application numbers CN201921408219.X ("A Device for Precisely Controlling the Production Length of Spiral Stirrups") and CN202320098225.X ("A Spiral Stirrup Forming Machine with Cutting Function"). Existing technologies require coiled steel bars, with numerous drive wheels and round rollers straightening and conveying the bars before bending. Each spiral stirrup is then CNC-controlled cutted.

[0004] However, for situations where the raw material consists of multiple straight steel bars, each of which is used to process a spiral bar, and the shape requirements for the spiral bar are not high, the existing automated processing technology loses its advantages of convenient processing and high production efficiency. Therefore, it is necessary to provide a simple processing device for raw materials consisting of multiple straight steel bars. Utility Model Content

[0005] The purpose of this invention is to provide a simple processing device for spiral reinforcing bars in steel cages to process multiple sections of straight reinforcing bars.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A processing device for spiral reinforcement cages includes a worktable, a motor, a bearing housing, a rotating spindle, an auxiliary shaft, and two fixed supports.

[0008] The motor and bearing housing are respectively mounted on the workbench;

[0009] The bearing housing rotatably supports one end of the rotating spindle via the bearing, and the other end of the rotating spindle is rotatably supported by the spindle bracket fixed on the worktable;

[0010] The motor is used to drive the rotating spindle to rotate;

[0011] The auxiliary shaft is arranged parallel to the main rotating shaft, and both ends of the auxiliary shaft are rotatably supported by fixed brackets fixed on the worktable.

[0012] The bottom of the auxiliary shaft is lower than the top of the main rotating shaft;

[0013] The rotating spindle has a straight steel bar fixing block near the bearing seat, which is used to clamp the head of the straight steel bar.

[0014] Furthermore, the straight steel bar fixing block includes a vertical plate and a cover plate, and the rotating spindle has a vertical plate and a cover plate near the bearing seat; the vertical plate is fixed to the outer surface of the bearing seat, and the cover plate is perpendicular to the top of the vertical plate; the rotating spindle, the vertical plate and the cover plate together form an opening facing the other end of the rotating spindle.

[0015] Furthermore, the workbench is provided with a U-shaped groove plate on its side, with the opening of the U-shaped groove plate facing outward.

[0016] Furthermore, the outer diameter of the auxiliary shaft is smaller than the outer diameter of the rotating main shaft.

[0017] Furthermore, the auxiliary shaft is a circular tube structure.

[0018] In the above technical solution, the present invention has the following beneficial effects:

[0019] During operation, the operator feeds the straight reinforcing bar at an angle between the rotating main shaft and the auxiliary shaft, with the length of the reinforcing bar forming an angle with the axis of the rotating main shaft. The bottom of the auxiliary shaft is lower than the top of the rotating main shaft to bend the straight reinforcing bar. As the rotating main shaft rotates the straight reinforcing bar, the auxiliary shaft also rotates, thus inputting the straight reinforcing bar. Attached Figure Description

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] It should be noted that the terms "above," "one end," "up," etc. used in this document indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Similar expressions are only for illustrative purposes and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "part," "two parts," etc. are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] like Figure 1-4 The apparatus shown is for processing spiral reinforcement cages, including a worktable 1, a motor 2, a bearing seat 3, a rotating spindle 4, an auxiliary shaft 5, and two fixed supports 6.

[0030] The workbench 1 is a table structure, and the motor 2 and bearing seat 3 are respectively set on the workbench 1. The workbench 1 is the mounting base for various parts of the processing device.

[0031] The bearing housing 3 supports one end of the rotating spindle 4 by the rotation of the bearing, and the other end of the rotating spindle 4 is supported by the spindle bracket fixed on the worktable 1 by the bearing and other connecting parts; the rotating spindle 4 is rotatably mounted on the worktable 1.

[0032] Motor 2 is used to drive the rotating spindle 4 to rotate; it is the power source of the rotating spindle 4 and can be connected to the rotating spindle 4 through a coupling or other mechanism.

[0033] The auxiliary shaft 5 is arranged parallel to the rotating main shaft 4, and both ends of the auxiliary shaft 5 are rotatably supported by fixed brackets 6 fixed on the worktable 1. The bottom of the auxiliary shaft 5 is lower than the top of the rotating main shaft 4. The distance between the outer surfaces of the rotating main shaft 4 and the auxiliary shaft 5 is greater than the diameter of the straight reinforcing bar. There is a straight reinforcing bar fixing block near the bearing seat on the rotating main shaft, which is used to clamp the head of the straight reinforcing bar, thus fixing one end of the straight reinforcing bar.

[0034] like Figure 4As shown, during operation, the operator feeds the straight rebar at an angle into the gap between the rotating spindle and the auxiliary shaft. The length direction of the straight rebar forms an angle with the axis of the rotating spindle, and the head of the straight rebar is high while the tail of the rebar is low during final processing. The straight rebar needs to be held continuously during the processing. The bottom of the auxiliary shaft is lower than the top of the rotating spindle to bend the straight rebar. The straight rebar fixing block secures the head of the straight rebar. When the rotating spindle drives the straight rebar to rotate, the friction between the auxiliary shaft and the straight rebar also causes it to rotate, thus inputting the straight rebar. Finally, the spiral rebar is removed from the rotating spindle after processing. Preferably, the straight rebar fixing block includes a vertical plate 71 and a cover plate 72. The vertical plate 71 and the cover plate 72 are located near the bearing seat 3 on the rotating spindle 4; the vertical plate 71 and the cover plate 72 are generally in the shape of a "7". The upright plate 71 is fixed vertically to the outer surface of the bearing housing 3, and is perpendicular to the axis of the rotating spindle 4. The cover plate 72 is perpendicular to the top of the upright plate 71; the rotating spindle 4, the upright plate 71, and the cover plate 72 together form an opening facing the other end of the rotating spindle 4. Figure 3 As shown, the head is first inserted into the opening. During the rotation of the opening, the height of the head from the outer surface of the rotating spindle is limited to maintain the curvature of the head. When processing each straight rebar, the head is first inserted into the opening. Due to the action of the rotating spindle and auxiliary shaft, the head will tilt upwards and thus get stuck in the opening. The upright plate 71 and the cover plate 72 rotate synchronously with the rotating spindle.

[0035] Preferably, the side of the workbench 1 is provided with a U-shaped channel plate, with the opening of the U-shaped channel plate facing outward. In practical applications, multiple straight steel bars are usually placed vertically and scattered on the side of the workbench surface. In order to prevent the straight steel bars from spreading out, the U-shaped channel plate can partially surround the multiple straight steel bars.

[0036] Preferably, the outer diameter of the auxiliary shaft 5 is smaller than the outer diameter of the main rotating shaft 4. This helps the spiral rib maintain its curvature.

[0037] The preferred auxiliary shaft 5 is a circular tube structure. This helps to save materials.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
